Be it known that l, LAWRENCE Cook, a residing at San and useful Improvements in a Wind Vane, of which the-'following is a specication.

M invention relates to improvements in a wind vane and particularly relates to a wind vane adaptedto be used in connection with aviation n and located` .in aerodromes and emergency landing fields- The object of my invention is to construct a wind vane which may be visible vfrom all angles and particularly from .aircraft ilying over the placewhere the windvane'is located, to indicate to the aviator the direction oit the wind close to the ground, which in'- ormaton will assist theaviator in making a safe landing by steering into the wind and thus .avoiding serious consequences by presuming that thegroundwind is blowing in the same direction as the a further object of my struct the wind vane so that it may be illuminated at night, showing dierent colors to identify the landing :field at night and by painting the wind vane with dierent colors which will be visible in day time; a ystill further object of 'my invention is to construct the wind vane in detachable sections, so that it may loe-shipped yconveniently and readily wind vane is necessarily large, being about forty feet long andeight feet in width, to make it visible' from high altitudes; and a still furthemobject of my invention is to construct a wind vane which is so. rigid iii construction as `to@ withstand severe weather conditions land at the. same time so very light in weight ythat it will turn upon-its pivoted bearing by a veryA slight wind pressure. v

'Fliese together-- with various other novel details of construction and arrangement of the parts, which will be more fully hereafter described and claimed, tion.

larger scale and s owing onlythe front half ofthe wind van Fig. 6, is a transverse section on line 6 Fig. 5; Fig. 7, is a transverse section on line 7-7 Fig. 5; Fig. 8, is a transverse section on line 8& 8 Fig. 5; and Fig. 9, is a transverse section, as, on line 7-7 Fig. 5, with the crossfpieccs removed and the sides folded together upon the cen-V tral rib, for storage or transportion purposes. A n

'lhe wind vane 10 has the general formation of an arrow, with'a pointed fronten-d and a V-shaped-rear end, as shown in Fig. 1. The sides l2 and y13 of the vane arefpositioned at an angle of forty-five degrees in relation to the central vertical plane so that from all angles. A light rigid frame work is used in constructingthe vane, over which frame is a covering of translucent material.

' llhe vane:I 1Q is supported and balanced upon a central bearing post 14 which is rigidly secured in a base 15, which may be the ground, a plat-form,'or the roof of a building. A ball bearing 16 is vprovided to reduce the friction between thegtop of the post 14 and the bearingplate 17 secured to the centical section on line 5 -5 Fig. 1, drawn on a post 14, bythe wind which may getI under the vane.

. An actuating vane or fin 24 is secured in a vertical position upon the rear end of the central rib frame '18' and projects su-fliciently above and beyond the rear of the wind vane proper, to be acted up.on bv the wind and turn the vane upon the pivot post, thus always holding the front end of the vane pointing into the wind.

'lllhe central longitudinal rib frame 18 consists of the upper members 25 and 26, see

Fig.- 5, and lower members 27 and '28, posts l29 and braces 30.` Sai-d central rib frame carries the weight of the vane. The central rib trame 18 `.iS Blade in section, preferable 1n 675 ble at night. Either"electrics-lights or oil two sections joined together adjacent to the '7l/ k Fi s. 3 and 7. and by the central cross piece 21, to which supporting post 14 by the bearing plate 1 parts 17 and 21, the rib frame members 25-26-27 and 28 are secured by bolts 32 and 33, or other suitable fastening devices by which the parts may be quickly attached and detached.

The sides 12 and 13, of the vane are made of a skeleton frame work 35, covered with canvas 36. The upper strips37 of the side frames 35 are detachably secured to the central rib frame. 18 by hinges 38 having slip bolts 39, which permit the side frames to be readily removed from the central rib 18, or folded against said rib 18, as shown in Fig.

' 9. rlhe lower edges of the side frames 35 are separated and the frames held out at an angle of forty-five degrees from' the central vertical yframe by the cross pieces 21-41 and 42, as shown in Figs. 3, 5, 6, '7 and 8. Detachable securing devices 45 are used to secure the side frames to the cross pieces, so that said parts may be readily disconnected. The

` fastening devices.

said cross pieces are also detachably secured to the central rib 18 by bolts 46 which may be readily removed to allow the -side frames to be folded together when the cross pieces are removed.

The side frames 35 are made. in sections corresponding in length with the length wof the sections into which the central rib frame 18 is divided, thus permitting the vane to be divided into convenient lengths for shipping purposes.

The front end of the vane consists of two triangular frames 48 and 49, also covered with translucent material. Said triangular frames 48 and 49 are secured to the ends of the side frames 35 by hinges 50, which permit them to be folded back upon the side frames, as shown in dotted lines Fig.'3. The central lrib frame 18 projects forward las shown in Fig. 5, and has a sloping ridge piece 52 to support the free edges of the triangular frames 48 and 49. rIhe latter kframes may be secured together at their free f* edges by a hasp and staple 53 which will permit of their being readily separated,

thus making the front of the vvane acces- "s'iblefor persons entering the vane to adjust the lights. The front extension pieces 52 and 54', of the central rib frame 18, are detacha'bly connected to the main 'portion of said frame 18 by bolts 55, or other suitable The end cross pieces 42lhave brackets, 56 secured thereto to which the wheels 2O are sef 'cured and the central'cross piece 21 carries Y arelmounted and extend beyond the sidesof.- the vane to better hold the vane and prevent extension brackets 57 oii which the wheels its rocking sidewise.

The vane yis illuminated to make it visilanternsGO may be used, such as shown in Iaving thus described my invention I claim and desire to secure by Letters Patent' 1. A wind vane comprising a frame work rotatably mounted, a longitudinal member forming part of the said frame work, and said longitudinal member comprising a display surface extending in a plane at an an gle to the central vertical plane of the frame work whereby said display surface may be visible rfrom a position directly above the wind vane 2.
